General Nathanael Greene Homestead Museum at Spell Hall, Providence

About 40 minutes outside of Providence, in the small community of Coventry, lies the Greene Homestead. Built in 1770 by the Revolutionary War hero himself, the place is surrounded by lovely gardens and overlooks the Pawtuxet River. The building has been converted into a museum; inside is a comprehensive history of the man and his exploits. War buffs of all kinds will marvel at the on-site cannon, and souvenirs can be had at the museum gift shop.
